A combustionless BTU meter utilizes Nuclear Magnetic Resonance (NMR) spectroscopy to measure the concentrations of the component parts of a heterogeneous gas. Measurement of the gas component concentrations allow for subsequent calculations of British Thermal Unit/Cubic Foot (BTU/CF) from the measured component parts. Static pressure and temperature are also measured. Gas concentrations are preferably combined with static pressure and temperature, to calculate other characteristics of British Thermal Unit/Pound (BTU/lb), molar mass, relative density, and absolute gas density. A method for measuring heat production is also disclosed.
